[0002] In the field of cloud computing data centers, with the development of internet technology, the demand for servers and storage servers is increasing, and the requirements for server stability and reliability are also becoming more stringent. Chassis monitoring systems play a crucial role in monitoring the overall operational status of the server. When a server powers on, the BMC (Baseboard Management Controller) system typically runs first, followed by the BIOS (Basic Input Output System) initializing the server system hardware and booting the server operating system. During the server operating system's operation, it monitors the server chassis through the IPMI (Intelligent Platform Management Interface). When the BMC system malfunctions or the IPMI is congested, the KCS (Keyboard Controller Style) interface cannot be created, preventing the server operating system from monitoring the chassis through the BMC, thus reducing the reliability and stability of the server system.

[0043] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] Reference Figure 1 The flowchart illustrates an embodiment of a keyboard controller style interface fault redundancy method according to the present invention, which may specifically include the following steps:

[0045] Step 101: Save the keyboard controller style interface information to flash memory.

[0046] Before the Basic Input / Output System (BIOS) is started, the keyboard controller style interface information of the circuit board can be stored in the flash memory from the BIOS code. The flash memory can be the BIOS's flash memory, allowing the BIOS to read it directly at startup.

[0047] Step 102: When the basic input / output system starts, obtain the digital integrated circuit mapping information.

[0048] Then, when the basic input / output system starts up, the CPLD (Complex Programmable Logic Device) mapping information, i.e. digital integrated circuit mapping information, can be obtained. The status of the input / output interfaces of the board management controller during normal startup can be reflected through this digital integrated circuit mapping information, thereby determining whether the board management controller has started up normally.

[0049] Step 103: Determine the status of the substrate management controller based on the digital integrated circuit mapping information.

[0050] Based on the digital integrated circuit mapping information, determine whether the status of the substrate management controller is normal.

[0051] Step 104: When the status of the substrate management controller is abnormal, the step of obtaining digital integrated circuit mapping information is repeated after a preset time interval until the first repetition number is reached. Then, the step of sending the substrate management controller status detection command to detect the status of the substrate management controller is repeated until the second repetition number is reached. Finally, a keyboard controller style interface is created based on the keyboard controller style interface information stored in the flash memory.

[0052] When the substrate management controller is determined to be in an abnormal state, after a preset time interval, the step of acquiring digital integrated circuit mapping information is executed again to determine the substrate management controller state using the new digital integrated circuit mapping information. The substrate management controller state is determined through multiple retries; if the substrate management controller state is still abnormal after the first retry count, a substrate management controller state detection command is sent to determine the state of the substrate management controller process, thereby determining the substrate management controller state. Then, multiple retries are performed again until a second retry count is reached, at which point the substrate management controller state is determined to be abnormal. At this point, a keyboard controller style interface is created based on the keyboard controller style interface information stored in flash memory, thereby forcibly creating the keyboard controller style interface. The preset time, the first retry count, and the second retry count can be set according to actual needs, and this embodiment of the invention does not impose limitations.

[0053] This invention embodiment stores keyboard controller style interface information in flash memory. When the Basic Input / Output System (BIOS) starts, it acquires digital integrated circuit (DIC) mapping information. Based on the DIC mapping information, it determines the status of the baseboard management controller (BMC). When the BMC status is abnormal, the step of acquiring the DIC mapping information is repeated after a preset time interval until a first repetition is reached. Then, the step of sending a BMC status detection command to detect the BMC status is repeated until a second repetition is reached. Finally, a keyboard controller style interface is created based on the keyboard controller style interface information stored in the flash memory. This invention embodiment, by pre-storing the keyboard controller style interface information in flash memory, ensures that the keyboard controller style interface information is preserved even during power failures and restarts or when the BIOS starts. Then, when the BIOS starts, or when the BIOS malfunctions or processes are blocked, the keyboard controller style interface can be created based on the stored keyboard controller style interface information. This allows the BIOS to monitor the chassis status through the keyboard controller style interface, improving the reliability and stability of the server system.

[0054] Reference Figure 2 The flowchart illustrates another embodiment of the keyboard controller style interface fault redundancy method of the present invention, which may specifically include the following steps:

[0055] Step 201: Save the keyboard controller style interface information to flash memory.

[0056] In this embodiment of the invention, the B keyboard controller style interface information used by the current substrate can be stored in flash memory, wherein the flash memory can be the flash memory of the basic input / output system.

[0057] Step 202: When the basic input / output system starts, obtain the digital integrated circuit mapping information.

[0058] When the basic input / output system starts up, it obtains the digital integrated circuit mapping information through the corresponding interface channel.

[0059] Step 203: Determine the status of the substrate management controller based on the digital integrated circuit mapping information.

[0060] The status of the substrate management controller is determined by the acquired digital integrated circuit mapping information.

[0061] Step 204: When the status of the substrate management controller is abnormal, the step of obtaining digital integrated circuit mapping information is repeated after a preset time interval until the first repetition number is reached. Then, the step of sending the substrate management controller status detection command to detect the status of the substrate management controller is repeated until the second repetition number is reached. Finally, a keyboard controller style interface is created based on the keyboard controller style interface information stored in the flash memory.

[0062] When the substrate management controller is in an abnormal state, the step of obtaining digital integrated circuit mapping information is repeated up to the first repetition number to determine the substrate management controller state multiple times. If the substrate management controller state is still not abnormal after multiple retries, a substrate management controller state detection command is sent to the basic controller to test whether there is a problem with the substrate management controller process and to determine the substrate management controller state. If the substrate management controller state is still abnormal after multiple retries, a keyboard controller style interface is created based on the keyboard controller style interface information stored in flash memory to achieve forced creation of the keyboard controller style interface.

[0063] Specifically, the step of repeatedly executing the step of acquiring digital integrated circuit mapping information after a preset time interval until the first repetition number is reached includes: periodically executing the step of acquiring digital integrated circuit mapping information according to the preset time to determine the status of the substrate management controller; when the status of the substrate management controller is abnormal, continuing to execute the step of acquiring digital integrated circuit mapping information until the first repetition number is reached; and interrupting the execution of the step of acquiring digital integrated circuit mapping information when the status of the substrate management controller is normal.

[0064] Specifically, after initially determining that the substrate management controller's state is abnormal, a preset time is waited before a second attempt is made to acquire digital integrated circuit mapping information. The newly acquired digital integrated circuit mapping information is used to determine the substrate management controller's state. If this determination indicates the substrate management controller's state is normal, then the subsequent acquisition of digital integrated circuit mapping information is interrupted. If this determination still indicates the substrate management controller's state is abnormal, after a preset time interval, the acquisition of digital integrated circuit mapping information is performed again, and the determination is repeated until the first repetition number of times the acquisition of digital integrated circuit mapping information is reached. Multiple retries are made for the substrate management controller. The interval time and the first repetition number can be determined based on actual conditions, such as an interval time of 5 seconds and a first repetition number of 5 times. This embodiment of the invention does not impose limitations.

[0065] Specifically, the baseboard management controller status detection instruction includes a device identifier acquisition instruction and a self-test instruction; the step of repeatedly executing the step of sending the baseboard management controller status detection instruction to detect the status of the baseboard management controller until a second repetition number is reached includes: sending the device identifier acquisition instruction to obtain an update status identifier fed back by the baseboard management controller; when the update status identifier is an update identifier, repeatedly executing the step of sending the device identifier acquisition instruction until a second repetition number is reached; when the update status identifier is an update identifier, sending the self-test instruction to obtain a hardware fault identifier fed back by the baseboard management controller; when the hardware fault identifier is empty, determining that the baseboard management controller status is normal; when the hardware fault identifier is a preset fault identifier, repeatedly executing the step of sending the self-test instruction until a second repetition number is reached, and then determining that the baseboard management controller status is abnormal.

[0066] In this embodiment of the invention, the status detection instruction of the baseboard management controller includes a device identifier acquisition instruction and a self-test instruction; the device identifier acquisition instruction can be a get deviceid (get identifier) ​​instruction, and the self-test instruction can be a getselftest (self-test) instruction.

[0067] In this embodiment of the invention, a device identifier acquisition command can be sent via the KCS channel of the LPC bus (Low Pin Count bus) to obtain the update status identifier fed back by the board management controller. The update status identifier is used to determine whether the BMC firmware is being updated. When the update status identifier is an update identifier, or when the update status identifier is empty, it is determined that the BMC firmware is being updated. After waiting for a preset time, the step of sending the device identifier acquisition command is repeated until a second repetition is reached.

[0068] When the update status flag is "not updated," it is determined that the BMC firmware is not in an update state. The input / output system can send a self-test command to obtain the hardware fault flag fed back by the baseboard management controller; this determines whether there is a hardware fault in the baseboard management controller. When the hardware fault flag is a preset fault flag, the step of sending the self-test command is repeated until a second repetition is reached to eliminate occasional false detections. If the hardware fault flag still exists after the second repetition, it can be determined that the baseboard management controller is in an abnormal state.

[0069] Furthermore, the step of repeatedly executing the step of sending the self-test command until the second repetition number is reached includes: periodically repeating the execution of sending the self-test command; when the hardware fault identifier is a preset fault identifier, continuing to execute the execution of sending the self-test command until the second repetition number is reached; when the hardware fault identifier is empty, interrupting the execution of sending the self-test command, and determining that the status of the baseboard management controller is normal.

[0070] In this embodiment of the invention, the step of sending the self-test command can be repeated periodically. During the execution, if the hardware fault identifier is detected to be empty, the step of sending the self-test command is interrupted to determine that the status of the baseboard management controller is normal. If the hardware fault identifier is continuously detected as a hardware fault identifier, the execution continues until the second repetition number is reached.

[0071] Furthermore, if the status of the baseboard management controller remains abnormal after multiple retries, the status of the baseboard management controller can be recorded to generate an exception log, which will facilitate subsequent troubleshooting.

[0072] Step 205: When the baseboard management controller is in normal status, obtain the baseboard management controller information and create a keyboard controller style interface based on the baseboard management controller information.

[0073] When the baseboard management controller is in normal status, relevant baseboard management controller information is obtained from the basic central processing unit. Based on the obtained baseboard management controller information, an intelligent platform management interface protocol is created, and a corresponding keyboard controller style interface is created, thus completing the keyboard controller style interface. Furthermore, information corresponding to the keyboard controller style interface at this time can be obtained and updated in the flash memory, thereby updating the keyboard controller style interface information in the flash memory.

[0074] This invention embodiment stores keyboard controller style interface information in flash memory; when the basic input / output system starts, it acquires digital integrated circuit mapping information; determines the status of the substrate management controller based on the digital integrated circuit mapping information; when the status of the substrate management controller is abnormal, it repeats the step of acquiring digital integrated circuit mapping information after a preset time interval until a first repetition is reached, and then repeats the step of sending a substrate management controller status detection command to detect the status of the substrate management controller until a second repetition is reached, and then creates a keyboard controller style interface based on the keyboard controller style interface information stored in flash memory; when the status of the substrate management controller is normal, it acquires substrate management controller information and creates a keyboard controller style interface based on the substrate management controller information. This invention pre-deposits keyboard controller style interface information into flash memory, ensuring that the information is preserved even during power outages, restarts, or the startup of the Basic Input / Output System (BIOS). When the BIOS starts, if there are BIOS malfunctions or process blockages, multiple retries can be performed. If an BIOS malfunction is confirmed, a keyboard controller style interface can be created based on the pre-deposited information. This allows the BIOS to monitor the chassis status through this interface. If the BIOS is functioning normally, it can acquire the baseboard management controller (BMC) information and create the keyboard controller style interface accordingly. This enables the creation of keyboard controller style interfaces for chassis status monitoring in various scenarios, improving the reliability and stability of the server system.

[0075] To enable those skilled in the art to better understand the embodiments of the present invention, an example is provided below to illustrate the embodiments of the present invention:

[0076] Reference Figure 3 This diagram illustrates the architecture of an application server as an example of a keyboard controller-style interface fault redundancy method according to the present invention. The server includes a central processing unit (CPU), a complex programmable logic device (CPLD), a baseboard controller (BMC), and a basic input / output system (BIOS). The BIOS communicates with the CPU via SPI (full-duplex synchronous serial bus). The CPU and BMC communicate via PCIe (high-speed serial computer expansion bus), I2C (two-wire synchronous serial bus), and LPC (low pin count bus).

[0077] After the server is powered on, the CPLD controls the BMC to start first. During BMC system startup, the BMC hardware is initialized, and the IPMI process is created. Then, the CPLD controls the CPU to power on, and the CPU loads the BIOS firmware to initialize the server hardware system. The keyboard controller style interface fault redundancy method is as follows:

[0078] 1. The BIOS code (Basic Input / Output System code) stores the BMC KCS (Baseboard Controller Keyboard Controller Style) information currently used by the motherboard in the BIOS Flash Nvram (Basic Input / Output System Flash Memory);

[0079] 2. When the BIOS starts, it checks the CPLD mapping to identify the interface status of the BMC during normal startup. If the BMC starts normally, it proceeds to step 3. If the BMC starts abnormally, it reads the CPLD mapping 50 times at 500ms intervals. If it is abnormal in all cases, the BMC is considered to be starting abnormally. The relevant abnormal log is recorded, and then the process jumps to step 5.

[0080] 3. During BIOS startup, a getdeviceid command is sent via the LPC's KCS IO port (keyboard controller style interface channel) to determine if the returned bmc status (baseboard server status) indicates that the BMC firmware is being updated. If the bmc status does not indicate that the BMC firmware is being updated, the BIOS initiates a getselftest command. If the bmc status indicates that the BMC firmware is being updated or the command does not return a response, a retry is initiated after 5 seconds, with a maximum of 5 retries.

[0081] 5. If the get selftest returns no hard fail (hardware failure) or firmware update status, create an IPMI transport protocol (Intelligent Platform Management Interface Protocol) using the obtained BMC information, and update the obtained BMC KCS information to the BIOS Flash NVRAM; if the get selftest returns a hard fail or firmware update status, or the command does not return, wait 5 seconds and initiate a retry, with a maximum of 5 retries.

[0082] 6. If steps 2 and 4 fail, use the BMC KCS related data stored in the BIOS Flash Nvram to force the creation of the IPMI transport protocol;

[0083] 7. After the IPMI transport protocol is successfully created, an ACPI SMPI table is created, and the KCS information is saved to the ACPI SMPI table (keyboard controller style interface).

[0084] It should be noted that, for the sake of simplicity, the method embodiments are all described as a series of actions. However, those skilled in the art should understand that the embodiments of the present invention are not limited to the described order of actions, because according to the embodiments of the present invention, some steps can be performed in other orders or simultaneously. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions involved are not necessarily essential to the embodiments of the present invention.
